Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187654, here are decompositions:

3 + 187651 = 187654
17 + 187637 = 187654
23 + 187631 = 187654
107 + 187547 = 187654
191 + 187463 = 187654
281 + 187373 = 187654
293 + 187361 = 187654
317 + 187337 = 187654

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 187,654 and was likely granted around 1875.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
